Jan 7, 2005 3:10 am: The line-level converter came today and it did the trick! Without it, levels were too low and during recording I was saturating about 11 or 12 bits of all 16 bits of dynamic range. But with it, I am saturating 15-16. Of course, this raises the noise floor to around -60dB, but since 8-bit audio cannot mathematically exceed a dynamic resolution of -48dB, I'll just do a noise cut at -48. Woohoo!

The Amiga has 2 8-bit converters per channel, and each of which has a 6-bit attenuator. The theoretical dynamic range is therefore 6 * (8+6+1) = 90dB. Of course the output is quite noisy, but it's much more than 48dB.

I assume it's too late now, but hopefully someone will have pointed this out already...
